Numerical simulation of flow-induced noise in external and internal flows

Vibro-acoustic analysis and modelling of cabin/cockpit interiors and payload bays

Aero-acoustic source identification

At RUAG Aviation we have experience with experimental determination of aircraft noise sources. Our wind tunnels can be instrumented with an array of 144 microphones to experimentally determine noise source maps.

Vibro-acoustic source identification

RUAG Aviation has experience and a track record of ground and flight testing with portable microphone arrays. Measurements in different platforms, such as business jets and helicopters, have been carried out with different goals: vibro-acoustic source identification, RCA (Root Cause Analysis) of noise issues, pre-buy acoustic inspection, development and validation of NVH (Noise, Vibration and Harshness) packages.

Numerical simulation of flow-induced noise

Flow-induced noise is numerically simulated at RUAG Aviation for both internal and external flows.
